Temperature-Dependent

Caption

This image shows the growth of an E. coli strain with the temperature-sensitive "Cryodeath" kill switch integrated into its genome. At 37°C, the kill switch is kept OFF, allowing the bacteria to grow at four different dilutions (the lowest on the most left and the highest on the most). However, at 22°C, it is turned ON, rapidly killing the bacteria at the same dilutions. Credit: Wyss Institute at Harvard University
